Coin Cell Battery Holder - 12mm (SMD)

This is the SMD version of PRT-07948, which is the unit we like to use as RTC backup and SRAM backup for GPS units. Holds battery in place with friction. The metal housing connects to the positive side of the battery and the PCB pad underneath is connected to the negative side.

    Will the SFE Eagle library be updated to include this and the other new parts you have added since April 13th 2010? please?

    Is these part have a datasheet. O couln't find these part in sparkfun library ?

      You'll have to double-check, but it should be:
      SparkFun-Electromechanical.lbr
      Device: BATTERY
      Package: BATTERY12MM

    I ordered some likes these from digikey and one note for potential buyers. They tend to lift pads, since the battery is being held in by the tension between the board and the contacts on the holder. Even using a through hole point with solder all the way through it will still lift pads on even fab house boards. I have had 2 boards that have never had a single pad lifted by them, and about 10 boards that after a while the pads just pop making them unusable.
    They don't stay even remotely if you only have solder on one side without the through hole added support.
    My advice, use the through hole parts, they stay in place and if you needed one side nice and flat like I did you can trim the short before soldering and maintain a fairly planar surface on the opposing side.

    Awesome, it looks like a cartoon cat!
